JPEG not displaying in MS Internet Explorer 7 or 8 ? I was puzzled. I checked the src link, re-uploaded the image…

Well, then I learned that JPEGs saved in the CMYK color model will not display in MS IE, while they do display in Firefox 3.x.

I guess saving JPEGs in CMYK is unusual, esp. for screen use. I assumed the file was in RGB, given that it was intended for the web.

Microsoft Internet Explorer 8.0 does not display JPG images with CMYK color mode
